THIS COMMAND REFERENCE NEEDS TO BE UPDATED.

Altimeter (Layer Information Extraction)

extract_max_mean_from_data_files

Creates CSV outputs which contain the max,mean,leading edge for the surface and bottom layer.

Posting/Publishing Commands

This command loads radar data and displays it for publications and presentations. It allows data from each radar system to be loaded in a synchronized fashion using the GPS time that the data was collected at and allows data from different times to be compared. It also supports detrending, elevation compensation, surface compensation, etc. See "run_load_data_by_gps_time.m" for an example of how to run the tool.

Initial Setup Example

For example, a accumulation radar data which is named 20110412_165620_20110412_165720 is the data that we want process. There are several steps required to be setup before running the 'load_data_by_gps_time.m' program.

1. Interpret the file name so as to get the 'time' inforamition (i.e. start hour, start minute, start year, start month...). The details about how to interpret the data file is availabe here!
2. Enable/disable different parameter flags based on the various requirment. There are sveral flags inside 'load_data_by_gps_time.m', such as detrending enable flag, elevation compensation flag and surface eliminating flag. Those flags are not necessarily set to be 'enable' status, it really depends on the different requirments.
3. Adjust the depth range value by changing the variable 'param.post.depth_rng' in the script. The depth range depends on the image of the accumulation radar data. Usurally, a proper depth range will give a clear observation for different layers under the surface.

Support Commands

get_raw_files
